We can see that both figures are rectangles. The area of a rectangle is calculated by multiplying the rectangle's length, l, times its width, w.
A = l w
To calclate the area of the Figure 1, we substitute 12 for l, and 8, for w.
The area of Figure 1 is 96 and the area of Figure 2 is 294.
We want to compare the scale factor of the side lengths and the ratio of the areas. A scale factor is the ratio of the lengths of two corresponding sides of two similar polygons. Let's find the scale factor!
In Part A, we found that the area of Figure 1 is 96 and the area of Figure 2 is 294. To find the ratio of the areas, we will divide the area of Figure 2 by the area of Figure 1.
